摘要： A surgical sagittal saw including a handpiece from which a planar guide bar extends. A saw blade is mounted to the distal end of the guide bar to move across the guide bar. Drive rods connect the saw blade to a drive assembly in the handpiece, which drive assembly reciprocates the drive rods. The drive rods oscillate the saw blade across the distal end of the guide bar. The saw is used with a cutting guide that is in a fixed position relative to the bone or hard tissue to be cut. A capture element is disposed adjacent the guide surface and holds the guide bar to the guide surface so the cut is made along the desired cut plane.

摘要： PROBLEM TO BE SOLVED: To provide a surgical arrow-like saw blade which generates only a minimum vibration in use, and by which excessive wear of a cutting guide being used together with the saw does not occur, and in addition, of which the dimension is comparatively small. SOLUTION: This surgical arrow-like saw blade 112 is used together with a surgical arrow-like saw 20, and extends by at least partially passing through a guide bar 110, and includes two driving rods 114 which are arranged in the guide bar and reciprocate in the guide bar in which each driving rod is a blade head equipped with two driving rods so as to be engaged with a driver unified with the surgical arrow-like saw, and the blade head has a tooth which is arranged on the outside of the distal end of the guide bar and has at least almost the same thickness as the thickness of the distal end of the guide bar. The distal end of the driving rod is connected with the blade head on both side of the blade head so that rocking of the blade head may be generated. COPYRIGHT: (C)2010,JPO&INPIT

摘要： A method for replacing a joint surface, which includes resecting a first portion of the joint surface to create a wall surface and inner resected surface. The wall surface (2006) separates the inner resected surface and a non-resected portion of the joint surface. Further included in the method is cutting a concave groove having a first radius into the wall surface, and engaging the concave groove with a periphery of a joint prosthesis. The periphery includes a second radius that is substantially the same as the first radius of the concave groove.

摘要： A blade assembly (22, 210) for use with a sagittal saw assembly comprising a handpiece (24) having a forwardly directed front face and a drive assembly (30, 34, 48) disposed inside said handpiece (24) is described. The blade assembly (22, 210) comprises an elongate guide bar (110, 212) adapted to, when coupled to the handpiece, extend forwardly from the handpiece front face and terminate at a distally directed face spaced from the handpiece front face. The guide bar (110, 212) includes a bottom bar (116, 218), an inner bar (118, 220) and an outer bar (120, 222) that are stacked together. The inner bar (118, 220) holds the bottom bar (116, 218) and the outer bar (22) in spaced relationship from each other, and contributes to the overall rigidity of the guide bar (110, 212). A saw blade (112, 214, 302) is movably attached to said guide bar (110, 212) between the bottom and outer bars (218, 222). Said saw blade (112, 214, 302) has teeth (168, 308) which extend outwardly beyond said guide bar distally directed face, and said saw blade has a thickness dimension defined transversely to the elongated direction of said guide bar (110, 212). A connecting member (114, 216, 312) extends in the space between the bottom and outer bars (218, 222) and has a first end adapted to be connected to the drive assembly (30, 34, 48) of the sagittal saw. A second end of the connecting member is connected to said saw blade (112, 214, 302) such that said connecting member (114, 216, 312), when driven by the drive assembly (30, 34, 48), is adapted to displace said saw blade (112, 214, 302) so that said teeth (168, 308) oscillate back and forth across said guide bar distally directed face. Said guide bar (110, 212) has a thickness dimension defined transversely to the elongated direction thereof, said thickness dimension being no greater than the thickness dimension of said saw blade (112, 214, 302). Said connecting member (114, 216, 312) and said saw blade (112, 214, 302) comprise a monolithic, one-piece component.

摘要： A bicruciate retaining tibial implant baseplate (100) includes a tibial baseplate with medial and lateral condylar portions (110, 105) configured to receive bearing inserts (200). The baseplate includes an anterior bridge (115) connecting the medial and lateral portions. A posterior wall (116) of the anterior bridge may be angled to provide downward force on a correspondingly angled anterior portion of the tibial eminence (345) when the baseplate is implanted. A method of preparing the tibia for implant includes a punch (380) and punch guide (360) configured to both cut the anterior tibial eminence and provide protection to the tibial eminence during resection of the proximal tibia.
